Question

An inductance $L$ , a capacitance $C$ and a resistance $R$ may be connected to an $A C$ source of angular frequency $ω$ , in three different combinations of $R C, R L$ and $L C$ in series. Assume that $ω L = \frac{1}{ω C}$ . The power drawn by the three combinations are $P_{1}, P_{2}, P_{3}$ respectively. Then,

P_{1} > P_{2} > P_{3}

Solution

The correct option is A $P_{1} = P_{2} = P_{3}$
The $L C$ circuit draws no power. When $ω L = \frac{1}{ω C} .$

The impedances of the $R C$ and $L R$ circuits are equal, and they draw the same power.
